For the past few years, Amazon has hosted an annual event called Prime Day in which the company offers millions of discounts on products it sells. The event is officially scheduled to being at midnight PT on July 15 and run for 48 hours, making it the longest one to date. Prime Day started back in 2015 and was a 24-hour event that kicked off at 3am ET and brought new deals with it every 5 to 10 minutes.

Over the years, this has evolved and grown, and last year Amazon offered over a million deals over the course of a 36 hour period, and has promised to do the same during this year’s event. In the past, Amazon has offered select periods of time and certain deals to be exclusive to users of its Voice Shopping services. These are done through an Alexa-enabled device like the Echo Dot, Fire TV, etc. If you don’t already own one of these, you may want to consider grabbing one before the event in case Amazon decides to offer these benefits again.
